Improvement in mounting lease-rods for looms



g Letters Patent No. 94,957, dated September 2l, 1869` IMPROVEMENT IN'. MOUNTING LEASE-RODS FOR LOOMS, 8cc.

` `The Schedule referred to in these Letters Patentvand making part of the same.

To all whom it fntaylconcem:

Be it known that I, WILLIAM A. IIAsrrNGs, of

Thorndike,` in the county of Hampden, and State Iof Massachusetts, have invented a new and fiiseful Improved iVarp-Index for Looms 5 and I do hereby de- "clare that the following is a full, clear, and exact description, thereof, reference being, had to the accompanyingdrawings, making a part of this specification, and. tothe letters of reference marked thereon, in whichi w i Figure l is a plan view of my invent-ion, as applied l to a loom.

My invention relates to av devicefor indicating to the operator the position and condition of the threads of the warp iii-weaving, so that he may the more readily and -seasonably adjust any threads which may become broken in the operations of weaving; and

It consists of any desirable number of rods, of a similar form as those now in use, attached at or near each end to` an elastic cordor strap, one end of said cord or strap being attached to some part of the loom d or its belongings.

In the drawings- A B is a frame, the endB may be considered as representing a roll, upon which the threads e c' are wound, While the end B may be considered to represent a roll, upon which is wound the cloth, as fast as it is woven, the process of weaving being carried on between the two. u

It will be seen, by reference tothe drawings, that l the threads marked c pass over the rod a', 'and under' the rod a, while the threads marked c pass under the iod a', and over the rod a. v p

This arrangement of the threads, which `is-now coin- `monly used, separates them so that the operator can the more readily see when the threads become dis.- arranged or broken, as is frequently the case; for, as the cloth is Woven, and-the ,threads are drawn from the usual warp-beam forward through the loom,these threads are always moreor less uneven, having knots and bunches upon them, and `very frequently become `snarled or knotted to' such an extent that as,` they are drawn -forward the knots catch against the rods, and

the threads, becoming checked intheir passage, be-

come broken, if not released. v

The objectoil my invention is to relieve the temporary stoppagein the passage of the threads through the loom, by giving to thel rods an elastic bearing or attachment. i y

This I accomplish by means of an ,elastic strap or cord, b, attached to each end of each rod a o', the other ,end of said strap or cord being' secured to any convenient part of the loom' at c.

One 'strap on each side may answer for all the rods, or one may be used to each rod, as may be most convenient and desirable. 4

If only one strap oneach side is used', the rods are attached to the strap at 't ft', by perforating the strap and insertingl the end' of the rod into the perforation,4

or in any other suitable manner.

A long, very elastic spiral spriig might be used to i accomplish the same result, but I prefer some other elastic material, as India rubber, as it is very much cheaper, and accomplishes the desired result.

The most commonnnethod of securing the rods is V.to use a leather-strap, with a weight attached, at one end, said` strap being secured'- to the opposite side of the loom to that at which my elastic strap is attached.

This leather strap, withits weight, is Ver-y machin the way, and interferes materially with the tendency which the rods alw( ys have to aocominodate themselves to the motion of the warp, and if this motion of the rods is interfered with, the cloth does not look as well.

It is also desirable, very often, in adjusting threads, to draw the 'rods back towards the side of the lo'om to which the elastic straps'arc secured, but by the use of a leatherstrap, the rods can only be moved one way; and another objection to weights attached to a strap is, that the weights are liable to get caught in loose warp, or other material, which is always more or less about a loom. p In my invention, the straps areup entirelyout of reach of other matter, and are not' at all liable to be interfered with. A

Oftentiines the attention of the operator is occupied ivith various other duties, and while so occupied, if a knot should` catch upon one of the rods, the elasticity of the'strap would permit the rod to be drawn By the use of this elastic warp-indexthe appearance ot" the cloth is very greatly improved, giving it a much smoother surface and Va thicker appearance.

In weavinw some kinds of oroods but a` sinffle rod is D b t* required, while in other cases sometimes three are required, but it is immaterialas to the number used, -v

I em :were that movable rods have heretofore been used as a Werp-index, but never, to my knowledge, has the device herein described been before known or used; and

Having, therefore, described my invention,

What I claim as new, and desire to secure by Letters Patent, isv An elastic Werp-index, consisting of one or 'more rods a, to each end of which is attached the spring b, securedv to a convenient piece upon the loom, eli construeted'endoperating substantially as and for the' purposes herein described end set forth.
